The book was A Dictionary of Terms Used in Medicine and the Collateral Sciences, 1887. It's quite amusing in places, really. Being a Victorian medical publication, it treads a fine line between Not Wanting To Discuss Certain Things and finding it actually needs to mention them.

So for potentially sordid terms like, say, "orgasm", we get such wonderfully vague definitions as

"...a term denoting evanescent congestive phenomena, which manifest themselves in one or in several organs at once."

I mean, that could describe anything from a blush, through a migraine, to hayfever, depending how you read it.
